SunGrains (Southeastern UNiversity GRAINS) is a cooperative research program that was initially established by five southeastern university small grain breeding programs in 2005. The SunGrains agreement was revised in 2011 and expanded to six institutions.

The mission of the SunGrains cooperative breeding program is to increase efficiency and productivity of the breeding programs to ensure development of superior varieties that serve all end users; to enhance graduate student training in applied and basic plant breeding and genetics research; and to ensure long-term viability of these programs by increasing opportunities for program funding through revenues and enhanced extramural funding.
